Application filed February 20, 1920. Serial No. 360,029.

T 0 aZZ whom it may concern:

Be it known that I, THOMAS F. MoCAM- nmnon, a citizen of the UnitedStates, residing at Akron, in the county of Summit and State of Ohio,have invented new and useful Improvements in Rims, of which thefollowing is a specification.

This invention relates to cross-cut or split demountable rims ofautomobile Wheels and the like and has particular reference to means forsecuring the abutting ends of the demountable rim together.

The primary object of the present invention is to provide an extremelysimple and easily manipulated means for securing the ends of demountablerims together.

With the above general objects in view and others that will becomeapparent as the nature of the invention is better understood, the sameconsists in the novel form, combination and arrangement of partshereinafter fully described, shown in the accompanying drawing andclaimed.

In the drawing forming a part of this specification, and wherein likereference characters indicate corresponding parts throughout the severalviews,

Figure 1 is a bottom plan View of a fragment of a split demountable rimshowing a means constructed in accordance with the present invention forsecuring the ends of said rim together, and

Figure 2 is a view substantially in central longitudinal section and inperspective of the device shown in Figure 1.

Referring more in detail to the several views, the present inventioncontemplates the provision of a very efficient and durable means forsecuring the ends 5 and 6 of a cross-cut or split demountable rimtogether so that they abut at their ends as at 7.

In carrying out the present invention, I rigidly attach an elongatedplate 8 t0 the rim end 6 by means of rivets 9 or the like so that theprojecting free end 10 of the plate 8 underlies the adjacent end 5 ofthe rim. The projecting end 10 of the plate 8 is reduced in width andoffset laterally as at 11 so as to provide a tongue 12 preferably ofrectangular form in plan snugly fitting in a correspondingly shapedopening 13 provided centrally in the rim end 5. This effectivelyconnects the two ends 5 and 6 and retains the same against separation,but in order to insure positively against disconnection of the ends 5and 6, means are provided for holding the tongue 12 within the opening13. This means preferably consists of a hook 14 which is pivoted as at15 to the rim end 5 and which is movable so that its free end 16 engagesthe under surface of the tongue 12 and prevents the latter from movingout of the opening 13. The free end of the hook 14 is arranged to swingunder the head of the stud 17 which is riveted or otherwise fastened tothe rim end 5 adjacent the opening 13, and the free end of the hook 14-snaps onto the shank of the headed stud 17 so that the hook ismaintained operatively positioned with its free end engaging the undersurface of the tongue 12.

A circular stud or projection 18 may be formed on the attached portionof the plate 8 for reception in a socket in the permanent rim of thevehicle wheel in the usual manner whereby the demountable him isretained against circumferential movement or creeping relative saidpermanent rim.

In operation, the rim ends 5 and 6 are brought together so that the sameabut as at 7, at which time the tongue 12 is brought into the opening 13by an outward or radial movement of the end 6 of the rim. The hook leisthen swung on its pivot 15 until its free end 16 is latched on the shankof the stud 17. The free end of the hook 1 1 then underlies the tongue12 and effectively prevents the latter from moving out of the opening 13in the rim section 5. It will thus be seen that I have provided anextremely simple and effective means for connecting the ends of splitdemountable rims and which may be very easily manipulated fordisconnection of the rim ends when necessary.

It will, of course, be understood that minor changes may be made in theform, combination and arrangement of parts without departing from thespirit and scope of the invention as claimed.

Having thus described my invention what I claim as new and desire tosecure by Letters-Patent is:-

1. In a demountable rim having abutting ends, an elongated plate rigidlysecured to the under surface of one of said rim ends so as to projectunder the other rim end, said other rim end provided with an opening,the free end of said plate comprising a circumferentially projecting,outwardly offset portionadapted to seat in said opening with the outerand inner face thereof alined with the corresponding faces of said rim,said other end provided on its inner face, at a point adjacent saidopening, with an inwardly projecting stud, an overhanging head on saidstud, a hook pivoted to said other rim end so that the free end thereofmay be swung under said head and over said outwardly oifset portion tohold the same in said opening.

2-111 combination with the abutting ends of a split demountable rim, aplate rigidly fastened to one of said ends and underlying the other end,an offset tongue formed on the free end of said plate, said other rimend being formed for reception of said tongue whereby separation of therim ends is'prevented, a headed stud rigidly fastened to said other rimend, and a hook pivoted to the last named rim end and movable across theunder surface of the latter, the free end of said hook being formed tosnap onto the shank of said stud when underlying the tongue of saidplate whereby said tongue is operatively maintained engaged with thesaid otherrim end.

In testimony whereof I have hereunto set
